Title: Flat face brushless motor
Inventor: ABE GORO
IPC: H02K21/24
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To reduce a driving current, by installing the winding start connection part of a stator coil in a stator yoke of the outer peripheral part of the stator coil. SOLUTION: A stator coil 18 is formed by using a rectangular coil. A winding start tip 20 is dipped in a solder tank or the like, and subjected to soldering. In a part 21 of the outer periphery which turns to winding end, an insulating coating film is peeled. This stator coil 18 is fixed to a stator yoke 19 by using adhesive agent or the like. The winding start tip 20 is made to get into the lower part of each stator coil, arranged so as to overlap with a winding start connection part 22 installed in a stator yoke 19, and connected with the outer peripheral part of the stator coil by using solder. As a result, a space for soldering is made unnecessary in the inner peripheral part of the stator coil 18, and the number of turns of the stator coil 18 can be increased, so that the driving current of a motor can be reduced.

A position of the screw is detected and compared with an established speed changeover position S1 and correcting position S1'. When the screw arrives at the correcting position S1', a speed-setting device aqpplies the next setting speed F2 and the pump 14 is changed over to the loaded state (the loaded states of the pumps 10, 12 are kept as they are). When the screw arrives at a speed changeover position S1, an electromag netic proportional valve is changed over to an opening corresponding to the set speed F2 and the pumps 10, 12 are put into a state of no load at the same time. Hereupon, the S1 is based on the following expression: S1'=S1+K.F1 provided that k is corre sponding to a time lag DELTAt until hydraulic oil based on the pump 14 arrives at the electromagnetic proportional valve.
